I killed her the first time around then felt bad and went back. When I did, the GODDAMN FLOWER KNEW. I think that was the point where I went from thinking of it as a clever game with a new concept to just viewing it in complete awe.

yesss I feel like the game only REALLY gets good after the second playthrough, and I tried to convince a friend to get a different ending, but he spared Toriel the first time through and he refuses to kill her, OOPs. I'm really looking forward to the finished game, summer 2014 can't come soon enough!!
